Grid infrastructure (/u01/ora/11.2.0/grid) and RAC Database software (/u01/app/ora/product/11.2.0/db_1) has been deployed. Single instance database has been moved from file system to ASM. Now trying to convert single instance database to RAC using DBCA but getting below error while doing step:

Use DBCA to Create an Image of the Single-Instance Database

ORA-01078: failure in processing system parameters

ORA-01034: oracle not available

$ lsnrctl status

LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 23-SEP-2013 15:17:03

No, "Use DBCA to Create an Image of the Single-Instance Database" isn't in that document.

From the document:

Before you use DBCA to convert a single-instance database to an Oracle RAC or an Oracle RAC One Node database, ensure that your system meets the following conditions:

It is a supported hardware and operating system software configuration.

It has shared storage: either Oracle Cluster File System or Oracle ASM is available and accessible from all nodes. On Linux on POWER systems, ensure that GPFS is available and accessible from all nodes.

Your applications have no design characteristics that preclude their use with cluster database processing

After check this conditions:
